Coping with Shit.

If someone is ungrateful and, you tell him that he's ungrateful....what then! You've called him a name, but nothings changed!

Once you know and accept as truth, there are no more doubts. Once there are no more doubts, there are no questions and hypothetical possibilities that are usually the basis for future plans. "What if the sun doesn't rise tomorrow" is never a scenario we plan for because we know and have accepted that it will. No doubts about that.
If you know and accept that your boss is an arsehole, then there are no doubts that you'll only get shit from him.
Agreed, watching another defecating in public is quite unsettling....But since you know its just this, one gets used to it and it ceases to affect. All the people shitting by the railway tracks. On a train journey, one so easily accepts what one doesn't like. Thats all that watching somebody Shit is all about. Once you know, just accept!
Shit happens. Its part of life. But when you are in sit then there are two options. You can devote your senses to determining the quality of the shit or... focus all your senses on creating the scenario of a long luxurious bath that would wash it all off. That's detachment and a form of sensate focus. I prefer the tangible experience on the latter though!
